EDI Equipment We Repair — By Category
EDI Product Lines We Repair
Our engineers are trained on the full EDI product range. Below are the major product families we service.
EDI Servo Amplifiers and Brushless DC Drivers
High-performance servo amplifiers for precision motion control in CNC machines, textile looms, and packaging equipment. Common faults include phase loss detection failures, commutation errors, and firmware corruption leading to loss of motor synchronization and erratic motion.
EDI AC/DC Industrial Power Supplies
Regulated power supplies for industrial control systems, rated 24VDC to 48VDC. Typical failures include capacitor degradation, voltage regulation drift, and protection circuit malfunction causing downstream device damage.
EDI Motion Control Boards and PLC Modules
Embedded motion controllers and programmable logic interface cards for multi-axis automation. Repair challenges include EEPROM failures, encoder signal conditioning issues, and communication protocol stack corruption.
EDI Stepper Motor Controllers and Drivers
Microstepping drivers and step/direction controllers for open-loop and closed-loop stepper applications in light industrial assembly. Failures often stem from thermal stress, microcontroller faults, and H-bridge transistor degradation.
EDI Industrial I/O and Signal Conditioning Modules
Digital and analog I/O cards, isolated relay modules, and sensor conditioning units for PLC integration. Common issues include relay contact wear, analog channel crosstalk, isolation barrier breakdown, and ESD damage.
EDI Encoder and Feedback Sensor Interface Cards
Quadrature encoder counters, resolver-to-digital converters, and analog feedback amplifiers for closed-loop servo systems. Repair scope includes counter overflow, signal noise immunity, and differential line driver failures.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common EDI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EDI equipment arriving at our workshop.
- ✓Servo amplifier phase loss and commutation error — Hall effect sensor misalignment, encoder signal noise, or firmware corruption in the commutation lookup table. EDI servo drives require precise 120-degree commutation timing; loss of even one phase input causes immediate motor cogging and control loop instability.
- ✓EDI power supply voltage droop and regulation failure — Electrolytic capacitor ESR rise due to thermal aging or production batch defect, combined with high inrush current during system startup. Symptomatic output sag typically triggers downstream PLC watchdog resets or servo drive fault codes.
- ✓Motion control board encoder signal loss and counter overflow — Quadrature encoder cable shielding failure, improper grounding of differential receiver inputs, or counter register overflow in high-speed multi-axis applications. Results in position tracking error and runaway axis motion in safety-critical machinery.
- ✓EEPROM corruption and lost parameterization — Power loss during firmware update, ESD event during maintenance, or flash memory wear-out in older EDI PLC modules. Boards may boot with default parameters, causing unpredictable behavior or complete control system hang.
- ✓Stepper driver thermal shutdown and H-bridge FET failure — Excessive phase current draw due to motor winding short, inadequate heatsinking in compact enclosures, or marginal PCB layout causing thermal hotspots. EDI microstepping drivers operating at rated current in high-ambient factories experience premature FET degradation.
- ✓Relay contact chatter and I/O module isolation barrier breakdown — Mechanical vibration in production lines causing relay reed contact bounce, or high-voltage transient coupled across isolation barrier due to inadequate snubbing on inductive loads. Results in false signal detection and unintended machine state changes.

Frequently Asked Questions — EDI Repairs
Do you repair EDI equipment anywhere in India?+
Yes. Synchronics repairs the complete EDI product range - servo amplifiers, power supplies, motion control boards, stepper drivers, I/O modules, and encoder interfaces. We offer pan-India pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, Indore, and all tier-1 and tier-2 cities. All repairs are performed in our 180-engineer facility in Vadodara, Gujarat, with typical turnaround of 3-5 working days.
Can Synchronics recover lost EDI parameterization and firmware from a corrupted board?+
Yes, in most cases. If your EDI PLC module or servo drive has lost its programming due to power failure or ESD event, Synchronics can recover the firmware via JTAG debug port, read-back flash memory contents, and reconstruct the parameterization database. We can also reprogram with your original hex files if you have backups. This service is critical for Indian automotive and textile plants that cannot afford extended downtime waiting for parameter re-entry.
What warranty do you provide on EDI equipment repairs?+
Synchronics provides a 12-month warranty on all repaired EDI boards and drives, covering the replaced component and the repair workmanship. Extended warranty options are available for critical machinery in continuous production environments. All repairs include comprehensive functional testing, load bank validation, and safe-state shutdown verification before dispatch.
Do you offer emergency same-day EDI repairs for production breakdowns?+
Yes. Synchronics operates a dedicated emergency repair queue for critical machines. If you have a servo drive, power supply, or motion controller failure stopping your production line, contact our Vadodara facility directly for same-day evaluation and rapid turnaround. We also stock common replacement units for loan during the repair period to minimize downtime on high-value equipment.
Can Synchronics repair older EDI legacy servo amplifiers and discontinued stepper drivers?+
Absolutely. Many Indian manufacturing plants still operate older EDI SA-40, SA-100, STEP-2A, and PSU-DIN series equipment. Synchronics specializes in legacy electronics repair and maintains an extensive inventory of vintage transistors, capacitors, Hall sensors, and connector types. Even if EDI has discontinued a product line, we can usually restore it to full functionality with component-level repair and functional equivalence substitution where necessary.
How do I send my EDI unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a EDI drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on EDI repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your EDI unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
